Goal: Protect, enhance, and restore California least tern occupied and historically occupied habitat to create resilient, self-sustaining populations that provide for persistence over the long-term (>100 years).
Management units: 1, 7
From 2017-2021, annually conduct predator control at breeding least tern colonies before and during the nesting season to improve fledgling success. Include tracking of predator-tern interactions to provide real-time data to improve control efforts during the breeding season.
